To all whom it may concern:

Be it known that l, Nici-lonas MARIE, citi- Zen of the United States,residingl at Peoria, in the county of Peoria and State of Illinois, haveinvented certain new and useful Improvements in Filtering Apparatus; andl do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appert-ains to make and use the same.

This invention relates to an apparatus for separating solid matter fromliquids, being adapted for separating slop in distilleries.

The invention has for its main object to erect a filter in whichthematerial to be filtered is entered under pressure at its bottomagainst the force of gravity whereby said pressure, and gravity, effectthe desired separation.

A further object is to provide a vertical type of filter-press oftapered form in which its small end is its bottom into which thematerial is pumped and forced upward toward the large end; and in whichthe exit for the solid materials is at the large end.

The invention has certain other objects and relates to certain detailsof construction as will be pointed out hereinafter.

In the accompanying drawing Figure 1 is a side elevation of myapparatus. Fig. 2 is a front elevation of the same. plan of the head ofthe apparatus with part thereof removed. Fig. l is a horizontal sectionof the apparatus on a larger scale than that shown in Figs. l and 2.VFig. 5 is a detail in perspective of a portion of the interior of oneof the sections. Fig. 6 is a plan of the interior surface of one of thesections, and Fig. 7 is a transverse section on the section shown inFig. G on line Y Y.

It is desirable at the present day to filter distillers and brewersslops to drive out the water and moisture and save the solid portionsfor a stock food, and the device about to be described is particularlyadapted for this use as well as the filtration of such other materialsas can be handled in a filtering apparatus of this class.

In many forms of presses now in use it is often difficult to obtain asteady filtration because the machine becomes choked thus rendering` itnecessary to take the machine apart to clear it of the packed materialbefore it can be used further. ln view of this and other disadvantageswell known to the Fig. 3 is a` distiller I have devised an apparatuswhichl cannot become packed or choked and I depend upon gravity and thepressure used` in entering the slop to the press to properly andcompletely drive olf all the water, while providing for the free exit ofthe solid pressed material.

ln the drawings A and B represent two sections which constitute the bodyof my apparatus each of which is provided with longitudinal flanges Aand B respectively for securing the sections together by means of boltsAC, there being suitable packing mate rial between the flanges (notshown) by which to constitute perfectly tight joints. As will be seenthe body as assembled is conical in form being tapered fromV its upperend toits lower end and is provided at both its top and bottom withflanges l) and E respectively, those at the bottom having bolted theretoa fitting F with which communicates a pipe Gr through which the slop ispumped into the press to be filtered. p

Secured to the top flanges D as by means of bolts D is a head H having acorresponding flange J said head having cast therewith a horizontalhousing K provided with a cap L; This horizontal housing is in the formof two half cylinders placed side by side and cast in one piece withineach of which is a conveyer indicated in broken lines at M, in Fig. 3, aportion of each shaft of said conveyers being indicated by the letter N.Both cylinders of said housing as shown by the opening at O, Fig. 3,communicate with the body A B and said housing K and its cap areprovided with corresponding fianges P and Q respectively, for securingthem together byvmeans of bolts R. The shafts N have their bearings in afront wall S of the housing and their opposite ends have suitablebearing on any convenient part of the machine. Outside the wall S theshafts are provided with beveled gears T with which mesh beveledpinio-ns U on a shaft V lying at right angles to said shafts N and whichhas its bearings upon a projection of said housing K substantially asshown. Parallel to this shaft V is a shaft Wv carrying at one end astepped pulley or cone 2 the opposite end of said shaft carrying apinion 3 which meshes with a gear 4: on one end of the said shaft V. Thedriving relation between the pinions V and the gears T is such that theconveyers are driven in opposite directions and the rear end ofthehousing K is pen for the discharge of the lInaterial from the conveyers.

Beneath the open end of the housing and beneath the discharge ends ofthe conveyers, is a hopper 5 for receiving and carrying away thematerial. rIhe inner surfaces of the body A B are provided with groovesa b c as shown in Figs. 4, 5, G and 7 which extend around the innersurface of each half or section, their ends terminating a short distancefrom the juncture of the sections. The grooves are preferably curveddownward from their ends as shown in Fig. 6 so that the middle thereofare their lowest points. At these points the grooves which are dividedinto groups are connected by central vertical grooves indicated by 6, 7and 8 each series of the grooves being separated from its neighbor byleaving a continuous rib at intervals, as for instance, at 9. Outside ofeach half of the body and preferably cast therewith is an enlargement A2and B2 through each of which extends a vertical passage A3 and B3respectively, with which the vertical grooves 6, 7 and 8 communicatethrough openings B6, Figs. 4 and 7 Lying upon and fitting the innerconcaved surface of the sections A B is a lining of perforated materiall0 constitutinga strainer and connected into the bottom of each of thevertical passages A3 and B3 is a pipe 11 for the discharge of water.

The .operation is as follows z-The slop is entered through the pipe G,the solid portions gradually fill it, while the water passes through thestrainer 10 into the passages 6, 7 and 8 and thence into the verticalpassages A3 and B3 through the openings B6 finding its outlet throughthe pipes 11 to the sewer. The solid portions since they find no outletare retained and, as just stated, gradually fill the press and when thelatter is full the compression due to the continued pump pressurevcauses the water to be squeezed out. At the top of the press thematerial, which is in a solid semi-dry state, is forced against theconveyers. By fiaring the body from its bottom upward the material cannever become packed so as to choke the press but will always clearitself. The flare permits the material to slowly move toward the exitand the conveyers, which serve to hold itl back sufficiently forcompression purposes, slowly eject it. The bulk of the water will, ofcourse, be immediately discharged by gravity upon entering the presswhile that held by the solid material will be driven off by the highpressure when the press is full.

In order that I may be enabled to readily reach the interior of theapparatus, which is of considerable length, I preferably support it upona floor or platform suspending it therefrom on trunnions 12 half ofwhich may be cast with each of the halves A B if desired, or castentirely with but one of them. These trunnions are preferably mountedina suitable bearing indicated at '13 which has provision for verticaladjusting through bolts 14. Then it is desired to take the machine apartthe bolts are removed from the fianges E at the bottom and from thefianges D at the top, and the head II and its housing K is raised freeof the press by means, for instance, of a chain 15 or tackle (notshown). This having been done, by turning the bolts 14 the entire presswill be raised to clear the fitting F and can then be tilted on itstrunnions to a horizontal position level with the floor that supportsit, the waste pipes being so arranged as to offer no interference tothis movement. Having been placed in this horizontal position the boltswhich clamp the fianges A and B together are removed and the upper halfof the cylinder removed. The strainer 1() can then be removed to exposethe remaining lower half of the filter. The reverse operation will placethe filter in position for performing its work as before.

For cleaning purposes water may be pumped into the device after closingthe discharge pipes 11; then by a reversal of the pump connection it maybe pumped out bringing with it all solid substances.

A filtering apparatus comprising a vertically disposed body having atapered bore whose small end is lowermost the said body being providedon its inner surface with a series of circumferential grooves, conduitsconnecting the grooves, a pump. connected with the small end of the bodyto introduce slop thereto, there being an opening communicating with theconduits for the escape of fluid, and an exit at the upper large end ofthe body through which the solid materials are positively delivered dueto pressure from said pump, and power driven means for governing thedischarge of the solids therethrough.
